Subject: [git pull] habanalabs pull request for kernel 5.18

Hi Greg,

This is habanalabs pull request for the merge window of kernel 5.18.
Although it adds small number of features, this pull request mainly
fixes multiple bugs in the code and also does some re-factoring to
better organize the code.

Full details are in the tag.

Thanks,
Oded

  habanalabs: remove deprecated firmware states (2022-02-28 14:34:50 +0200)

----------------------------------------------------------------
This tag contains habanalabs driver changes for v5.18:

- Add new feature of recording time-stamp when a completion
  queue counter reaches a target value as determined by the
  userspace application. This is used by the graph compiler
  to accurately measure the time it takes for certain workloads
  to execute, which helps to fine-tune future compilations.

- Add two new attributes to sysfs that expose the VRM and
  f/w OS version

- Add a delay to the reset path that allows the driver to
  receive and handle additional events from the f/w before
  doing the reset. This can help when debugging why a reset
  event was received from the f/w.

- Re-factor some of the sysfs code in the driver. Mainly,
  move functions from hwmgr.c to more relevant files and
  totally remove hwmgr.c file.

- Fix multiple bugs such as races, use-after-free, ignoring
  error codes, etc.

- As usual, multiple minor changes and small fixes.
